Question

What are the x-intercept(s) of the graph of y + 30 = x2 + x?

(−5, 0) and (6, 0)

(−5, 0) and (−6, 0)

(5, 0) and (−6, 0)

(5, 0) and (6, 0)

Answer 1

To find x-intercept take the value of y as 0 and then solve the 2 quadratic equations that you get to get the 2 points on the x-axis :)
Understood? :)

Answer 2

first, solve the equation for "y"
